Research Interests

1. Entanglement theory and fault-tolerant quantum information processing. Research interests about this subject focus on: quantification of entanglement measures; dissipative dynamics of entanglement within structural environments; fault-tolerant schemes for quantum manipulations; analytical solution and dynamical control to time-dependent quantum systems.

2. Quantum statistical mechanics and renormalization group theory. Research of this line focuses mainly on: NRG algorithms to 1D and 2D quantum lattice systems; characterizing quantum states via matrix product state representation; description of hidden order and critical behavior for quantum systems with phase transitions.
